To, all whom it may cozicem;

Be a known that 1;, WILLIAM L. MOFAJB:

' LAND, a citizen of the United States, residing at Fairlield, in the county of Wayne and State of Illinois, have invented new and the draft cable.

'useful- Improvements in Concrete Mixers and Spreaders, of which the following is a specification.

This invention relates to concrete. iiixmg, and spreading machines, the object inview being to provide a machine in which the ingredients oi the concrete, are mixed in a thorough and. expeditious manner, and by means of. which the concrete, while 1.11. a. 118- tic condition, may be laid. and sprea the machine, as it iszmoved along, the machine embodying a motor which actuates the mixing elements and. also propels the. ma.- chine periodically under the manual control oi: the operator. A further object of the invention .is toprovide a machine of such constructlon that it may be laterally expanded and contracted in accogdancejwith the. width of thewalk he-i i lei means of the construction hereinafter desoribed, a large amount of labor and time,

as well as material is" saved.

' With the above and other objects. in view, the invention consistsv in the construction, combination and arrangement of parts, will be hereinafter more fully described, illustrated in the accom anying drawings, andpointed out in the c' ims hereunto appended. 1

In the drawings: Figure 1 is a plan view of the machine. of the same, looking toward the chain side. Fig. 3 is a side elevation taken from the op posite side. Fig. 4 is a vertical longitudinal section through the machine. Fig. 5 is a cross section on the line 5-5 of Fig. 1 6 is a longitudinal section of one of the. cross bars. Fig. 7 is a longitudinal section of the winding drum and clutch. Fig. 8 is. a longitudinal section of one of} the truckaxles. Fig- 9 is a longitudinal section through the compressing roller. Fig. 10. is a detail section of the clutch of the. counter shaft. 11 is a reduced. side elevation of the mac ine, showing the arraugemelikgf f The machine, as, a whole, is supported upon and adapted to. move, lengthwise of a pair oi parallel guide rails. 1 and 2, each of whl h- 1s s pported emiheld fixed 123 means s ec alisms at Letters may. hrii i a iq filed 1m 1. 191.2- aem He 'ZQ Q Fig. 2 is a side elevation couonx m 11mm AND surnames.

oi a plurality at legs 3, pointed as. S own "and adapted to be driven into the ground at opposite sides of the walk or other sur-- face to. helaid in. concrete.

The rails are, of course, located at a dis ance apart equal to the width of the machine and the wall; to be laid, and in addi two to their function as guide railsfor the.

truck, they serve as lateral gagles for the oncrete, as it, is dumped, from t and spread, and als as depth gages f e machine,

regulating the depth. or thicknessof the concrete, and the height of the top surface .thereoi from, th fourriletion.

o The machine comprises main longitudinal, side bars 4, conne ted hythe front andreerre s ars being connect tothe ars by angle corner braces 7.. Additional cross; bars 8' and 9- connect the aide bars 4:, at Points term diate. the end cross bars 5 and I end cross bars 5. and 6,-res e'ctively, the said.

In order o p vide for the ate al expension and contraction of the frame of the gmac me, and In der to adapt the machine -1 to ork o dlfi'erent widths, all oi the cr s 'bars. are made telescope, or in other words, ea h f so d bars. c ns sts of over apping and relatlvely slldable sections, together with lampmgm ans, such as ha ts, for

holding the same at the desired adjustment,

as illustrated in the drawings,

Arranged near the front of he machine is a. semi-cylindrical trough 10, while another similar trough 11 is arranged near the rear of the ma hine, These tro 11s are inur :naled upon shafts 12. and "3, extending :ftransverselyofthe machine and j rnal in suitable bearings 14;. Each of said shaft-S. zoarries a. lurality (if-mixing blades 15,.

This motor may be of the gasolene or electric or other type, as may-be found most expedient.

Connected to the forward trough 10 1s a hand lever 28, by means of which said trough may be turned over for dumping the contents thereof through the bottom of the machine. The rear trough 11 equipped with a corresponding hand lever 29, to be used for the same purpose, namely,'to dump the rear trough 1 Arranged in front'of the forward trough 10 is a cable drum 30 journaled in suitable bearings on the side bars 4 of the frame, and provided at oneend with a pulley wheel 31 normally loose thereon, but adapted to be thrown into engagement with the shaft 32' of the drum 30 by means of a clutch 33, shifted by means of a hand lever 34.

From the wheel 31 a belt 35 passes rearward around a pulley 36 on the projectin end of the counter shaft 20. Another clutci 37 is employed to throw the belt wheel 21 into and out of engagement with the shaft 20, said clutch being controlled by a hand lever 38. The machine is provided with a pair of axles 39 and 40, upon which are mounted truck wheels 41 which travel on the rails l and 2, hereinabove referred to, A draft cable 42 winds upon the drum30 at one end, and extends forward around a pulley 43 mounted at a suitable point in advance of the machine, the cable passing from said pulley 43 back to the truck to which it is connected, at the points 44.

It will be understood from't-he foregoing, that the motor drives the counter shaft 20,

which in turn drives the shaft 32 of the drum, when the clutch 33 is thrown in, and

in this way the machine, asia whole, is propelled or drawn along the ground, as the concrete is dumped from the troughs, thereby permitting the cross bars 26 and 6 to.

acted upon by the spreader bars, said roller being arranged between the front and rear troughs, as shown. To facilitate the lifting said parts comprises overlapping and rela-' tively slidable members or sections, as clearly shown in the drawings, this being done to enable the machine, as a whole, to be expanded and contracted laterally in accordance with the width of thelwork to be performed by the machine.

Cement, sand and gravel, or any other suitable ingredients are dumped into the troughs and subjected to the action of the mixing mechanism, first in a dry state, water being subsequently added in the proper quantity, to bring the mixture to a plastic or proper condition. Themixing troughs are then reversed or dumped one at atime, by means of the dumping levers described,

after which the troughs are returned to their receiving positions for other batches of macrete, as it is laid and rolled, and also serve as depth gages, by reason of the wheels 41 traveling upon said rails. The operation, above referred to, is continued and repeated until the concrete walk is laid, thereby saving a large amount of labor and time, and ,efiegting the utmost economy in the material use What is claimed is:

-1, In a concrete mixing-- and spreading machine, a truck, a motor mounted thereon, a rotary mixer embodying a horizontal shaft extendlng transversely of the truck and geared to the motor, a semi-cylindrical mixing trough journaled on the shaft of the rotary mixer, means for turning and dumping said trough, and concrete spreading means.

4:. In a concrete mixing and spreading machine, a truck embodying a laterally expansible frame, a motor mounted -thereon, a rotary mixer embodying a horizontal shaft extending transversely of the truck frame and geared to the motor, a longitudinally extensible semi-cylindrical dumping mlxlng trough journaled onsaid shaft, and a longitudinally extensible spreader, A

5. In a concrete mixing and spreading machine, a truck embodyingalaterally exansible frame, a motor mounted thereon, a rotary'mlxer embodying a'horiz ontalshaft extendlng transversely of the truck frame and geared to the motor, a longitudinally extensible semi-cylindrical dumping mixing trough 'journaled on said shaft, concrete spreading means, and a longitudinally ex tensible roller.

In testimony whereof I afiix my signature in presence of two witnesses.
